You might want to consider forming a non-profit for non-technical ownership/governance of the project (that can receive donations etc), or alternatively moving the new open source project under a fiscal sponsor like SPI or Software Freedom Conservancy.

Still much to figure out. The project is still fairly immature in general.
As far as hardware and funding goes, it's sort of sustainable now through not demanding very much in either, but more of both would no doubt be necessary to grow much farther. It's a bit claustrophobic not really having a proper CI machine or test instance for example.
